• DDK/WDM developing problem ... driver won't load on x64 windows platform

  - by user295975

  Hi there! I am a beginner at DDK/WDM driver developing field. I have a task which involves porting a virtual device driver from x86 to x64 (intel). I got the source code, I modified it a bit and compiled it succesfuly with DDK (build environments). But when I tried to load it on a ia64 Windows7 machine it didn't want to load. Then I tried some simple examples of device drivers from --http://www.codeproject.com/KB/system/driverdev.aspx (I put '--' to be able to post the hyperlink) and from other links but still the same problem. I hear on a forum that some libraries that you use to link are not compatible with the new machines and suggested to link to another similar libraries...but still didn't worked. When I build I use "-cefw" command line parameters as suggested. I do not have an *.inf file asociated but I'm copying it in system32/drivers and I'm using WinObj to see if next restart it's loaded into the memory. I also tried this program ( http://www.codeproject.com/KB/system/tdriver.aspx ) to load the driver into the memory but still didn't worked for me. Please please help me...I'm stuck on this and my deadline already passed. I feel I'driving nuts in here trying to discover what am I doing wrong.

• Access problems with System.Diagnostics.Process in webservice

  - by Martin

  Hello everyone. I have problems with executing a process in a webservice method on a Windows Server 2003 machine. Here is the code: Dim target As String = "C:\dnscmd.exe" Dim fileInfo As System.IO.FileInfo = New System.IO.FileInfo(target) If Not fileInfo.Exists Then Throw New System.IO.FileNotFoundException("The requested file was not found: " + fileInfo.FullName) End If Dim startinfo As New System.Diagnostics.ProcessStartInfo("C:\dnscmd.exe") startinfo.UseShellExecute = False startinfo.Arguments = "\\MYCOMPUTER /recordadd mydomain.no " & dnsname & " CNAME myhost.mydomain.no" startinfo.UserName = "user1" Dim password As New SecureString() For Each c As Char In "secretpassword".ToCharArray() password.AppendChar(c) Next startinfo.Password = password Process.Start(startinfo) I know the process is being executed because i use processmonitor.exe on the server and it tells me that c:\dnscmd.exe is called with the right parameters Full command line value from procmon is: "C:\dnscmd.exe" \MYCOMPUTER /recordadd mydomain.no mysubdomain CNAME myhost.mydomain.no The user of the created process on the server is NT AUTHORITY\SYSTEM. BUT, the dns entry will not be added! Here is the weird thing: I KNOW the user (user1) I authenticate with has administrative rights (it's the same user I use to log on the machine with), but the user of the process in procmon says NT AUTHORITY\SYSTEM (which is not the user i use to authenticate). Weirdest: If i log on to the server, copy the command line value read from the procmon logging, and paste it in a command line window, it works! Reading procmon after this shows that user1 owns the dnscmd process. Why doesn't user1 become owner of the process started with system.diagnostics.process? Is the reason why the command doesn't work?

• Problem calling web service from within JBOSS EJB Service

  - by Rob Goodwin

  I have a simple web service sitting on our internal network. I used SOAPUI to do a bit of testing, generated the service classes from the WSDL , and wrote some java code to access the service. All went as expected as I was able to create the service proxy classes and make calls. Pretty simple stuff. The only speed bump was getting java to trust the certificate from the machine providing the web service. That was not a technical problem, but rather my lack of experience with SSL based web services. Now onto my problem. I coded up a simple EJB service and deployed it into JBoss Application Server 4.3 and now get the following error in the code that previously worked. 12:21:50,235 WARN [ServiceDelegateImpl] Cannot access wsdlURL: https://WS-Test/TestService/v2/TestService?wsdl I can access the wsdl file from a web browser running on the same machine as the application server using the URL in the error message. I am at a loss as to where to go from here. I turned on the debug logs in JBOSS and got nothing more than what I showed above. I have done some searching on the net and found the same error in some questions, but those questions had no answers. The web services classes where generated with JAX-WS 2.2 using the wsimport ant task and placed in a jar that is included in the ejb package. JBoss is deployed in RHEL 5.4, where the standalone testing was done on Windows XP.

• Why does ActiveMQ hold messages that should be deleted from Topic?

  - by rauch

  I use ActiveMQ as Notification System(Pub/Sub model). On server: if any changes of data occur, Server send this updated data (File) to Topic using BlobMessages. There are few Clients, that subscribe on this Topic and get updated File if it exsist in Topic. The problem is that all of BlobMessages, that were sent to Topic, are hold by ActiveMQ all time. this.producer = new ProducerTool.Builder("tcp://localhost:61616?jms.blobTransferPolicy.uploadUrl=http://localhost:8161/fileserver/", "ServerProdTopic").topic(true) .transacted(false).durable(false).timeToLive(10000L).build(); this.consumer = new ConsumerTool.Builder("tcp://localhost:61616", "ServerConsTopic").topic(true) .transacted(false).durable(false).build(); consumer.setMessageListener(this); The File is sent: connection = createConnection(); session = createSession(connection); producer = createProducer(session); BlobMessage blobMsg = ((ActiveMQSession) session).createBlobMessage(resource); blobMsg.setStringProperty("sourceName", resource.getName()); producer.send(blobMsg); if (transacted) { System.out.println("Producer Committing..."); session.commit(); } Where createProducer is: protected Connection createConnection() throws JMSException, Exception { ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url); //connectionFactory.getBlobTransferPolicy().setUploadUrl("http://localhost:8161/fileserver/"); Connection connection = connectionFactory.createConnection(); connection.start(); ((ActiveMQConnection) connection).setCopyMessageOnSend(false); return connection; } All, that could be useful I set as need: Session.AUTO_ACKNOWLEDGE; Non-Durable Subscription; TimeToLive = 9000; JMSDeliveryMode = Non-Persistent; What I have at runtime: in ActiveMQ directory: ~/apache-activemq-5.3.0/webapps/fileserver/ tere are all File, that where delivered and not delivered to Subscribers. Why? Sometimes Server send Big Files about 1 GB....And even this Files are hold at that directory, Even after stopping Subscribers(Clients), Publisher(Server) and ActiveMQ Broker.

• Analyzing Windows crash dumps generated on XP/32 machines with Win7/64 ?

  - by Martin

  We have a problem with analyzing our Windows crash-dumps that were created on customer Windows XP/32 boxes on our development machines. Many of our development machines are now Win7/64 boxes, but it appears that the crash-dumps generated under Windows XP cannot full resolve their binary dependency, thereby leading to warnings when displaying the call stacks in Visual Studio (2005). For example, the msvcr80.dll cannot be resolved when loaded from a Win7 machine when the dump was generated on Windows XP: On XP, the WinSxS path appears to be C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.4053_x-ww_e6967989\msvcr80.dll -- on Win7, the WinSxS path to the same DLL version seems to be: x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4053_none_d08d7da0442a985d (I got this info from a forum thread on codeguru that link to an msdn article.) Visual Studio (2005) can now no longer correctly resolve the binaries for the crash-dump. How can I get Visual Studio to resolve all the correct binaries for my dump file? Note: I have already correctly set up the symbol server. The public symbols for most system DLLs (kernel32.dll, etc) and our symbols of our own DLLs are correctly loaded. It is just that the symbols of DLLs that reside in the WinSxS folder are not loaded, because it appears that Vista/7 uses a different path scheme for these DLLs than XP does and therefore Visual Studio cannot find the dll (not the pdb) on the local dev machine and so cannot load the corresponding symbols for the dump file.

• Connecting to SFTP service via Java Runtime process

  - by ohseekay

  Under my project, I have a Java class file, inside of which I have a routine which executes the following external SFTP script file: #!/bin/sh echo "cd AV/OASIS" >> sftp echo "put $1 $2" >> sftp echo "get AV/OASIS/$2 $3$2" >> sftp echo "bye" >> sftp /usr/local/bin/sftp -b sftp id@domain cat /dev/null > sftp exit 0 The Java code which executes the script file is as below: String script = "full path of script"; Process p = Runtime.getRuntime().exec(script + " " + param1 + " " + param2 + " " + param3); However, I'm not sure why, but the log generated by the class file always shows the error "Host key verification failed. Connection closed." I'd isolated that line in the script which connected to the remote machine, and ran it on the local machine (where this class file and script file are stored), and the command executed successfully I'd manually run the command which the Java class file will execute and it also tested okay: $ script.sh param1 param2 param3 I'd tried to look up the error message on the Internet, and apparently it seems to have something to do with known_hosts. Could this be the reason, or is there something else I'm missing? Thanks so much!

• Render multiple control collections in ASP.NET custom control

  - by Monty

  I've build a custom WebControl, which has the following structure: <gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server"> <Contents>(controls...)</Contents> <Footer>(controls...)</Footer> </gws:ModalBox> The control contains two ControlCollection properties, 'Contents' and 'Footer'. Never tried to build a control with multiple control collections, but solved it like this (simplified): [PersistChildren(false), ParseChildren(true)] public class ModalBox : WebControl { private ControlCollection _contents; private ControlCollection _footer; public ModalBox() : base() { this._contents = base.CreateControlCollection(); this._footer = base.CreateControlCollection(); } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Contents { get { return this._contents; } } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Footer { get { return this._footer; } } protected override void RenderContents(HtmlTextWriter output) { // Render content controls. foreach (Control control in this.Contents) { control.RenderControl(output); } // Render footer controls. foreach (Control control in this.Footer) { control.RenderControl(output); } } } However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property. I'll get the HttpException: Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'. Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently? Thanks for replies.

• Windows Live Messenger Activity SDK: Is it possible to use jQuery?

  - by Cheeso

  There's an SDK that lets developers build "activities" and games for use in Windows Live Messenger. The basic approach is to build a web app, that gets approved and hosted by Microsoft. questions Anyone done this? Can you use jQuery in that web app? how do you debug the thing, running within Windows Live Messenger? EDIT: I tried using jQuery, but couldn't get it to do much of anything. I also couldn't debug it at all, when running within the IM client. The IE8 F12 debug tools are not available in that context. I believe the embedded browser was silently not loading external script, and then silently throwing exceptions. So I backed off to use only script in the .HTM file. Since it is Windows Live Messenger, the embedded browser is IE, so the generality made possible in jQuery isn't strictly necessary. I was able to use old-skool DHTML interfaces to get done, what I needed. I'm still interested in seeing examples of what other people have produced in the way of WLM Activities or games, using the Messenger Activity SDK. I think Flash is possible, and I think XAML is also possible, but I haven't seen source code examples for any of those.

• Skip makefile dependency generation for certain targets (e.g. `clean`)

  - by Shtééf

  I have several C and C++ projects that all follow a basic structure I've been using for a while now. My source files go in src/*.c, intermediate files in obj/*.[do], and the actual executable in the top level directory. My makefiles follow roughly this template: # The final executable TARGET := something # Source files (without src/) INPUTS := foo.c bar.c baz.c # OBJECTS will contain: obj/foo.o obj/bar.o obj/baz.o OBJECTS := $(INPUTS:%.cpp=obj/%.o) # DEPFILES will contain: obj/foo.d obj/bar.d obj/baz.d DEPFILES := $(OBJECTS:%.o=%.d) all: $(TARGET) obj/%.o: src/%.cpp $(CC) $(CFLAGS) -c -o $@ $< obj/%.d: src/%.cpp $(CC) $(CFLAGS) -M -MF $@ -MT $(@:%.d=%.o) $< $(TARGET): $(OBJECTS) $(LD) $(LDFLAGS) -o $@ $(OBJECTS) .PHONY: clean clean: -rm -f $(OBJECTS) $(DEPFILES) $(RPOFILES) $(TARGET) -include $(DEPFILES) Now I'm at the point where I'm packaging this for a Debian system. I'm using debuild to build the Debian source package, and pbuilder to build the binary package. The debuild step only has to execute the clean target, but even this causes the dependency files to be generated and included. In short, my question is really: Can I somehow prevent make from generating dependencies when all I want is to run the clean target?

• TeamCity with TFS - workspace problems

  - by Tom

  Hi, We have been using CC.NET as our CI server for a month or so now, which has worked ok with TFS. In the config we were able to specify the TFS server, username, password, project and workspace which is all good. Now we are moving over to TeamCity mainly because it just seams more solid and is much nicer to use. The problem is getting it work with TFS. For the purpose of this, both the workspace and machine name are "BuildMachine", username is "BuildUser" TFS project is "$/Project/Dev/Website" I seam to have set it up correctly, I think, as when testing the connection it is successful. When I run a build I get a TFS error: "RunBuildException when running build stage UpdateSourcesFromServer." It goes on to say: "No matched workspaces were found. Will recreate workspace and perofming clean checkout." It then tries to create a new workspace something like this: TeamCity-S-sqa9qe2aulx22gz4rzkogl5kr/BuildUser It tries to set up some mappings and then fails because: "The working folder C:\ is already in use by the workspace BuildMachine;BuildUser on computer BuildMachine". This seams ok as this is the workspace that CC.net was using, and c:\project\dev\website is the path to the project. The problem is, why didn't TeamCity pick this up and use this workspace? Why does it try to create its own new one? Any idea how I can fix this? Thanks

• Strange File Upload issue with asp.net site on a web farm

  - by Coov

  I have a basic asp.net file upload page. When I test file uploads from my local machine, it works fine. When I test file uploads from our dev machine, it works fine. When I deploy the site to our production webfarm, it behaves strangely. If I access the site from off the network, I can load file-after-file without issue. If I access the site from within our network, I can load the first file just fine but any subsequent files result it a bad sequence of commands error. I'm not sure if this is web farm issue, a network issue, or something else. It feels like a connection is not being disposed of properly but it doesn't make sense why everything works fine remotely. Markup: <asp:FileUpload ID="FileUpload1" runat="server" Width="350px" /> <asp:Button ID="btnSubmit" runat="server" Text="Upload" onclick="btnSubmit_Click" /> Code: if (FileUpload1.HasFile) { FtpWebRequest ftpRequest; FtpWebResponse ftpResponse; ftpRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://ftp.myftpsite.com/" + FileUpload1.FileName)); ftpRequest.Method = WebRequestMethods.Ftp.UploadFile; ftpRequest.Proxy = null; ftpRequest.UseBinary = true; ftpRequest.Credentials = new NetworkCredential("username", "password"); ftpRequest.KeepAlive = false; byte[] fileContents = new byte[FileUpload1.PostedFile.ContentLength]; using (Stream fr = FileUpload1.PostedFile.InputStream) { fr.Read(fileContents, 0, FileUpload1.PostedFile.ContentLength); } using (Stream writer = ftpRequest.GetRequestStream()) { writer.Write(fileContents, 0, fileContents.Length); } ftpResponse = (FtpWebResponse)ftpRequest.GetResponse(); Response.Write(ftpResponse.StatusDescription); }

• I'm trying to grasp the concept of creating a program that uses a MS SQL database, but I'm used to r

  - by Sergio Tapia

  How can I make a program use a MS SQL server, and have that program work on whatever computer it's installed on. If you've been following my string of questions today, you'd know that I'm making an open source and free Help Desk suite for small and medium businesses. The client application. The client application is a Windows Forms app. On installation and first launch on every client machine, it'll ask for the address of the main Help Desk server. The server. Here I plan to handle all incoming help requests, show them to the IT guys, and provide WCF services for the Client application to consume. My dilemma lies in that, I know how to make the program run on my local machine; but I'm really stumped on how to make this work for everyone who wants to download and install the server bit on their Windows Server. Would I have to make an SQL Script and have it run on the MS SQL server when a user wants to install the 'server' application? Many thanks to all for your valuable time and effort to teach me. It's really really appreciated. :)

• Simple ASP.NET MVC views without writing a controller

  - by Jake Stevenson

  We're building a site that will have very minimal code, it's mostly just going to be a bunch of static pages served up. I know over time that will change and we'll want to swap in more dynamic information, so I've decided to go ahead and build a web application using ASP.NET MVC2 and the Spark view engine. There will be a couple of controllers that will have to do actual work (like in the /products area), but most of it will be static. I want my designer to be able to build and modify the site without having to ask me to write a new controller or route every time they decide to add or move a page. So if he wants to add a "http://mysite.com/News" page he can just create a "News" folder under Views and put an index.spark page within it. Then later if he decides he wants a /News/Community page, he can drop a community.spark file within that folder and have it work. I'm able to have a view without a specific action by making my controllers override HandleUnknownAction, but I still have to create a controller for each of these folders. It seems silly to have to add an empty controller and recompile every time they decide to add an area to the site. Is there any way to make this easier, so I only have to write a controller and recompile if there's actual logic to be done? Some sort of "master" controller that will handle any requests where there was no specific controller defined?

• Persistent warning message about "initWithDelegate"!

  - by RickiG

  Hi This is not an actual Xcode error message, it is a warning that has been haunting me for a long time. I have found no way of removing it and I think I maybe have overstepped some unwritten naming convention rule. If I build a class, most often extending NSObject, whose only purpose is to do some task and report back when it has data, I often give it a convenience constructor like "initWithDelegate". The first time I did this in my current project was for a class called ISWebservice which has a protocol like this: @protocol ISWebserviceDelegate @optional - (void) serviceFailed:(NSError*) error; - (void) serviceSuccess:(NSArray*) data; @required @end Declared in my ISWebservice.h interface, right below my import statements. I have other classes that uses a convenience constructor named "initWithDelegate". E.g. "InternetConnectionLost.h", this class does not however have its methods as optional, there are no @optional @required tags in the declaration, i.e. they are all required. Now my warning pops up every time I instantiate one of these Classes with convenience constructors written later than the ISWebservice, so when utilizing the "InternetConnectionLost" class, even though the entire Class owning the "InternetConnectionLost" object has nothing to do with the "ISWebservice" Class, no imports, methods being called, no nothing, the warning goes: 'ClassOwningInternetConnectionLost' does not implement the 'ISWebserviceDelegate' protocol I does not break anything, crash at runtime or do me any harm, but it has begun to bug me as I near release. Also, because several classes use the "initWithDelegate" constructor naming, I have 18 of these warnings in my build results and I am getting uncertain if I did something wrong, being fairly new at this language. Hope someone can shed a little light on this warning, thank you:)

• Java OutOfMemoryError message changes when trying to create Arrays of different sizes

  - by Gordon

  In the question by DKSRathore How to simulate the Out Of memory : Requested array size exceeds VM limit some odd behavior was noted when creating an arrays. When creating an array of size Integer.MAX_VALUE an exception with the error java.lang.OutOfMemoryError Requested array size exceeds VM limit was thrown. However when an array was created with a size less than the max but still above the virtual machine memory limit the error message read java.lang.OutOfMemoryError: Java heap space. Testing further I managed to narrow down where the error messages changes. long[] l = new long[2147483645]; exceptions message reads - Requested array size exceeds VM limit long[] l = new long[2147483644]; exceptions message reads - Java heap space errors I increased my virtual machine memory and still produced the same result. Has anyone any idea why this happens? Some extra info: Integer.MAX_VALUE = 2147483647. Edit: Here's the code I used to find the value, might be helpful. int max = Integer.MAX_VALUE; boolean done = false; while (!done) { try { max--; // Throws an error long[] l = new long[max]; // Exit if an error is no longer thrown done = true; } catch (OutOfMemoryError e) { if (!e.getMessage().contains("Requested array size exceeds VM limit")) { System.out.println("Message changes at " + max); done = true; } } }

• jQuery - Callback failing if there is no options parameter

  - by user249950

  Hi, I'm attempting to build a simple plugin like this (function($) { $.fn.gpSlideOut = function(options, callback) { // default options - these are used when no others are specified $.fn.gpSlideOut.defaults = { fadeToColour: "#ffffb3", fadeToColourSpeed: 500, slideUpSpeed: 400 }; // build main options before element iteration var o = $.extend({}, $.fn.gpSlideOut.defaults, options); this.each(function() { $(this) .animate({backgroundColor: o.fadeToColour},o.fadeToColourSpeed) .slideUp(o.SlideUpSpeed, function(){ if (typeof callback == 'function') { // make sure the callback is a function callback.call(this); // brings the scope to the callback } }); }); return this; }; // invoke the function we just created passing it the jQuery object })(jQuery); The confusion I'm having is that normally on jQuery plugins you can call something like this: $(this_moveable_item).gpSlideOut(function() { // Do stuff }); Without the options parameter, but it misses the callback if I do it like that so I have to always have var options = {} $(this_moveable_item).gpSlideOut(options, function() { // Do stuff }); Even if I only want to use the defaults. Is there anyway to make sure the callback function is called whether or not the options parameter is there? Cheers.

• Getting started with massive data

  - by Max

  I'm a math guy and occasionally do some statistics/machine learning analysis consulting projects on the side. The data I have access to are usually on the smaller side, at most a couple hundred of megabytes (and almost always far less), but I want to learn more about handling and analyzing data on the gigabyte/terabyte scale. What do I need to know and what are some good resources to learn from? Hadoop/MapReduce is one obvious start. Is there a particular programming language I should pick up? (I primarily work now in Python, Ruby, R, and occasionally Java, but it seems like C and Clojure are often used for large-scale data analysis?) I'm not really familiar with the whole NoSQL movement, except that it's associated with big data. What's a good place to learn about it, and is there a particular implementation (Cassandra, CouchDB, etc.) I should get familiar with? Where can I learn about applying machine learning algorithms to huge amounts of data? My math background is mostly on the theory side, definitely not on the numerical or approximation side, and I'm guessing most of the standard ML algorithms don't really scale. Any other suggestions on things to learn would be great!

• Request for the permission of type 'System.Web.AspNetHostingPermission' when compiling web site

  - by ahsteele

  I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines I would change the machine's .NET Security Configuration to trust the local intranet. I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

• Publish failed using Ant publisher (Eclipse/datanucleus).

  - by aronp

  Dear All, I am being driven mad the following (apparently hard) error from eclipse. Publish failed using Ant publisher Resource is out of sync with the file system: '/MyServlet/build/classes/com/inver/hotzones/database/BaseNetworkData.class'. I have seen comments on similar errors where refreshing eclipses view of the project helps but it is not helping me. Have tried cleaning the project, removing it from the webserver, deleting war files but cant seem to clear it. I have reset my TMPDIR variable so that it uses a directory on the same filesystem as that appeared to be another possible cause. The error occurs on classes which have been enhanced by datanuculeus. I have auto-enhance on the project. The other references to this problem indicate that it is due to Eclipses view of the project being out of step with the filesystem, and I am guessing that this has something to do with thedata nucleus enhancement. Any ideas? Thanks. I am using Eclipse 3.5.2 with latest datanucleus pluggins.

• What is optimal hardware configuration for heavy load LAMP application

  - by Piotr Kochanski

  I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).

  - by Vamsi

  Recently I am having problems with installing rcov gem on my windows (vista Home Basic environment), so after googling I found one solution and that is gem install rcov -v 0.8.1.1.0 #version that installs without errors gem update rcov #update to the latest version, in my case rcov-0.8.1.2.0-x86-mswin32 But this solution didn't worked on my colleague's system (windows xp) and after that we came to know about RubyInstaller devkit for winddows But that dev kit is not working on my vista, when I tried gem install rcov in my command prompt, it game me this error, C:\Users\Vamsi>gem install rcov Building native extensions. This could take a while... ERROR: Error installing rcov: ERROR: Failed to build gem native extension.ERROR: Failed to build gem native extension. D:/Spritle/Programs/Ruby/bin/ruby.exe extconf.rb creating Makefile nmake 'nmake' is not recognized as an internal or external command, operable program or batch file. Gem files will remain installed in D:/Spritle/Programs/Ruby/lib/ruby/gems/1.8/ge ms/rcov-0.9.8 for inspection. Results logged to D:/Spritle/Programs/Ruby/lib/ruby/gems/1.8/gems/rcov-0.9.8/ext /rcovrt/gem_make.out So after that my colleague tried to install nmake as well but it was throwing some other error. Can some one suggest a better solution for solving this problems for all windows environments? I am aware of cygwin for windows but I am not sure that is an 100% solution either.

• How do I import and call unmanaged C dll with ansi string "char *" pointer string from VB.net?

  - by Warren P

  I have written my own function, which in C would be declared like this, using standard Win32 calling conventions: int Thing( char * command, char * buffer, int * BufSize); I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere): Imports Microsoft.VisualBasic Imports System.Runtime.InteropServices Imports System Imports System.Text Namespace dllInvocationSpace Public Class dllInvoker ' tried attributes but could not make it build: ' <DllImport("Thing1.dll", False, CallingConvention.Cdecl, CharSet.Ansi, "Baton", True, True, False, True)> Declare Ansi Function Thing Lib "Thing1.dll" (ByVal Command As String, ByRef Buffer As String, ByRef BufferLength As Integer) Shared Function dllCall(ByVal Command As String, ByRef Results As String) As Integer Dim Buffer As StringBuilder = New StringBuilder(65536) Dim retCode As Integer Dim bufsz As Integer bufsz = 65536 retCode = Thing(Command, Buffer, bufsz) Results = Buffer Return retCode End Function End Class End Namespace The current code doesn't build, because although I think I should be able to create a "buffer" that the C Dll can write data back into using a string builder, I haven't got it quite right. (Value of type System.Text.STringBuilder cannot be converted to 'String'). I have looked all over the newsgroups and forums and can not find an example where the C dll needs to pass between 1 and 64kbytes of data back (char *buffer, int bufferlen) to visual basic.net.

• Applets failing to load

  - by Roy Tang

  While testing our setup for user acceptance testing, we got some reports that java applets in our web application would occasionally fail to load. The envt where it was reported was WinXP/IE6, and there were no errors found in the java console. Obviously we'd like to avoid it. What sort of things should we be checking for here? On our local servers, everything seems fine. There's some turnaround time when sending questions to the on-site guy, so I'd look to cover as many possible causes as possible. Some more info: We have multiple applets, in the instance that they fail loading, all of them fail loading. The applet jar files vary in size from 2MB to 8MB. I'm told it seems more likely to happen if the applet isn't cached yet, i.e. if they've been able to load the applets once on a given machine, further runs on that machine go smoothly. I'm wondering if there's some sort of network transfer error when downloading the applets, but I don't know how to verify that. Any advise is welcome!

• Writing language converter in ANTLR

  - by Stefan

  I'm writing a converter between some dialects of the same programming language. I've found a grammar on the net - it's complex and handles all the cases. Now I'm trying to write the appropriate actions. Most of the input is just going to be rewritten to output. What I need to do is parse function calls, do my magic (rename function, reorder arguments, etc) and write it. I'm using AST as output. When I come across a function call, I build a custom object structure (from classes defined in my target language), call the appropriate function and I have a string that represents the transformed function that I want to get. The problem is, what I'm supposed to do with that string? I'd like to replace the .text attribute of the enclosing rule, but setText() is only available on lexer rules and the rule's .text attribute is read-only. How to solve this problem? program : statement_list { output = $statement_list.text; } ; //... statement : expression_statement // ... ; expression_statement : function_call // ... ; function_call : ID '(' { /* build the object, assign name */ Function function = new Function(); //... } ( arg1 = expression { /* add first parameter */ } ( ',' arg2 = expression { /* add the rest of parameters */ } )* )? ')' { /* convert the function call */ string converted = Tools.Convert(function); // $setText(converted); // doesn't work // $functionCall.text = converted; // doesn't work } ;

• How do I find the module dependencies of my Perl script?

  - by zoul

  I want another developer to run a Perl script I have written. The script uses many CPAN modules that have to be installed before the script can be run. Is it possible to make the script (or the perl binary) to dump a list of all the missing modules? Perl prints out the missing modules’ names when I attempt to run the script, but this is verbose and does not list all the missing modules at once. I’d like to do something like: $ cpan -i `said-script --list-deps` Or even: $ list-deps said-script > required-modules # on my machine $ cpan -i `cat required-modules` # on his machine Is there a simple way to do it? This is not a show stopper, but I would like to make the other developer’s life easier. (The required modules are sprinkled across several files, so that it’s not easy for me to make the list by hand without missing anything. I know about PAR, but it seems a bit too complicated for what I want.) Update: Thanks, Manni, that will do. I did not know about %INC, I only knew about @INC. I settled with something like this: print join("\n", map { s|/|::|g; s|\.pm$||; $_ } keys %INC); Which prints out: Moose::Meta::TypeConstraint::Registry Moose::Meta::Role::Application::ToClass Class::C3 List::Util Imager::Color … Looks like this will work.
